The UR8CH is a digital input/output expansion module manufactured by GE Multilin for the UR family universal protection relays. It delivers multiple isolated digital input points and relay output contacts to extend the relay’s capacity for status acquisition, alarm signaling and trip control in power protection systems. This module adopts isolated circuit design to suppress electromagnetic interference in harsh substation environments. It supports built-in channel diagnostics for real-time fault detection. We supply surplus original and fully tested refurbished UR8CH modules with worldwide shipping and pre-shipment functional testing.
